Got another CRC warning today. I know that the usual recommendation is to not worry about these errors unless they continue to increase. Mine are now up to 3 over a period of about 6 months or so. Not sure if that is worth worrying about?

 

SMART report attached.

Not so much need to worry with so low frequency of transfer errors. The error detection is quite robust and right now you might get a short transfer paus of maybe a tenth of a second every two months. If the number of errors are higher, then it's a reason to worry because with too many transfer errors the probability of a broken transfer not being caught will increase significantly when there is a high frequency of transfer errors. CRC can find 100% transfers errors when each transfer has a single, short, burst of incorrect bits. But with really bad cables, the burst length could sometimes be too long - or there could be two error bursts in the same transfer - and then CRC will not manage. So people who see the counters ticking up on a daily basis should most definitely care and correct the issue at the soonest.

 

You might have had a power surge resulting in one transfer being damaged and restarted.

Or possibly you have cross talk between two cables.

Thanks. I might still replace the sata cable next time I have the case open.
